An attorney for top Hillary Clinton aide Huma Abedin responded for the first time to the FBI taking additional “investigative steps” into the Democratic presidential nominee’s use of a private email server Monday, claiming that her client did not know that her emails were on a computer that belonged to her estranged husband, Anthony Weiner.

“From the beginning, Ms. Abedin has complied fully and voluntarily with State Department and law enforcement requests, including sitting for hours-long interviews and providing her work-related and potentially work-related documents,” Abedin’s attorney Karen Dunn said in a statement released Monday night.

Dunn said Abedin first learned the FBI was looking into emails on the laptop Friday, after agency director James Comey sent a letter to Congress informing them that new evidence that emerged from a separate investigation “appear to be pertinent” in the Clinton email investigation, which was originally closed in July.

“She only learned for the first time on Friday, from press reports, of the possibility that a laptop belonging to Mr. Weiner could contain emails of hers. While the FBI has not contacted us about this, Ms. Abedin will continue to be, as she always has been, forthcoming and cooperative,” Dunn said in her statement.

Abedin has told colleagues she does not know how her emails ended up on her estranged husband’s computer and was shocked when she learned the FBI discovered them on Weiner’s computer, Politico reports.

Abedin has been one of Clinton’s closest aides for decades, having first worked for Clinton in 1996 as a 19-year-old White House intern.

Comey is facing criticism from top Democrats for notifying Congress about the new review less than two weeks before the presidential election. In a heated letter to Comey released Sunday, Senate Democratic leader Harry Reid accused the FBI director of holding back “explosive” information about Donald Trump’s close Russian ties and possibly violating the Hatch Act, which bars government officials from using their positions to influence an election.
